Insufficient input values supplied by engine in dxWDL 1.02

[pkaleta]

I'm working on porting my workflow to dxWDL 1.02. I have the following definition (redacted):

workflow my_workflow {
    String x
    ...
    Boolean use_foo = false

    call bar {
        input: ...
    }
    if (use_foo) {
        call foo as foo_task {
            input: f_in=bar.out
        }
    }
    File result = select_first([foo.out, bar.out])
    ...

task foo {
...
}

task bar {
...
}

I'm getting this error when trying to run it:

  bar.out )  Environment:     x -> WomString(2)
  bar.out -> WomSingleFile(dx:

It looks like foo is not available in the select_first() call. This construct used to work fine in the previous version of the dxWDL (0.81.6)
